An innovative combination of architecture and nature that creates a sustainable and green urban environment. With a total surface area of 755 m², this vertical forest consists of two main parts: 535 m² of vegetated surface on the façade and 220 m² of enclosures.
The objective of project
The project achieves a maximum height of 12 metres and a maximum width of 50 metres. To guarantee its stability, a solid self-supporting metal structure made of 45 tonnes of galvanised steel is used. This structure has 22 vertical frames made up of 140×140 mm tubular profiles, distributed over 4 levels of 2.5 metres in height each.

Description of the proposal
The area of the mixed vegetated façade is 535 m² and includes different elements. 450 m² of hydroponic modules with rockwool substrate are used, allowing a wide variety of plants to be grown. In addition, 85 m² of climbing plants are used which grow on a metal mesh, giving the structure a green and natural appearance. Fifteen large trees of nine different species are also suspended above the façade, adding beauty and diversity to the project. In total, around 22 000 plants are used, including 7 climbing plant species, 13 hanging species and 20 shrub species.
To ensure adequate irrigation of all plants, a drip irrigation system is implemented. This system consists of 11 irrigation sectors and uses 500 linear metres of drip irrigation pipe. In addition, 2 pumps are installed for water recirculation and fertigation. It is important to note that the project aims to be self-sufficient in water consumption. To achieve this, 13 accumulation tanks of 2,000 litres each are used, located inside the self-supporting structure. This allows an irrigation autonomy of up to 15 days, and even 7 days during the driest months.
In addition, the Caixaforum Vertical Forest project includes the restoration of 360 m² of façade surface, restoring the beauty and functionality of the structure and promoting sustainability and the presence of nature in urban environments.
